Huckabee says Obamacare 'not working'

The Affordable Care Act is "not working out very well," Mike Huckabee said Sunday.

Appearing on "Fox News Sunday," the former Republican governor of Arkansas said President Barack Obama is making "arbitrary changes" to the law because it is failing, referring to the Obama administration's latest change to the ACA, which suspended the individual mandate for people whose policies have been canceled.

Huckabee, a potential presidential candidate in 2016, said most families under the law are now seeing rising premiums, despite the Obama administration's claims that the law would reduce costs. He also said the president is losing credibility on the issue, citing Obama's winning the Politifact award for lie of the year for his statement that, "If you like your health careplan, you can keep it."

Huckabee, a frequent critic of Obamacare, said the president should not have "skewed" the marketplace by lumping in the insured with uninsured. Instead, Huckabee said, the president should have exclusively "approach[ed] the problem of the uninsurables."

On his own Fox News show earlier this month, Huckabee spoofed Obamacare with an ACA-themed song, set to the tune of “The Twelve Days of Christmas,” in which carolers sang “On the first day of Christmas, Obamacare gave to me, a doctor I can’t keep.”
